| 摘 要： | 采用液相沉淀法,通过表面活性剂进行分散,制备了-βCuSCN纳米粉体。讨论了反应温度、反应物浓度及表面活性剂对粉体的影响,用X射线衍射(XRD)、透射电镜(TEM)和激光粒度分析仪对粉体进行了表征。结果表明,最佳反应温度为80℃,最佳反应物浓度均为0.2 mol/L;当聚乙二醇400(PEG400)添加量为1.5%时,分散效果最好,制备的粉体平均粒径为40 nm左右。

| Abstract: | β-CuSCN nano-powders were prepared by liquid precipitation method,and were dispersed by surfactant.The influence of temperature,concentration and surfactant on the particles was investigated with X-ray diffraction analysis(XRD),transmission electron microscope(TEM) and Laser Particle Sizer.The results showed that the optimal temperature is 80 ℃,the optimal concentration of all reactants is 0.2 mol/L.The better dispersion was observed and the grain size is about 40 nm when the amount of polyethylene glycol 400(PEG400) was 1.5%. |
